Genomic and Phenotypic Classification of Staphylococcus Species Isolated From Delhi Air

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Multiple Staphylococcus spp. were isolated from the outdoor polluted air of the Indian Capital, New Delhi. The bacterial samples were collected from 6 different locations, and the whole genome of four Staphylococcus isolates was sequenced in their entirety. This study presents the comparative genomic analysis of these four isolates.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds
